The copper didn't drop out until it hit the steel cone, because it was still held in solution as a soluble salt, due to too much free acid in solution. If you run that again with the nails, the result will probably be better. All the nail metal that is eaten up is making iron salts, and when there's more iron left but no more free acid, it will start replacing salts of the less reactive metals, leaving them as free metal.

Now what if he did this with a basic mix? Is he still using the sulfur at the end: 34:24? Or what if he used nearly none for that matter? Would the oxide then reduce to Cu, and oxidize the Fe? He also mentions using a less basic was better for nearly everything in the beginning. You are right though. Too much free acid/base will continue to keep salts as salts

@@matthewcurry3565 He could try putting some charcoal (the good stuff, not "brickettes") in the crucible to convert some of the metal oxides to carbon dioxide/monixide gasses. That's how a lot of metals are recovered industrially, but I don't think his crucible will get hot enough to recover all types of metal. That's probably similar to what's going on with melted sulfur in the mix too. The sulfur picks up oxygen, forms sulfate salts with the various metals, more easily with the more reactive metals, of course, and then loses excess oxygen as sulfur dioxide (probably). I think the workarounds he's trying to perform, due to variability of his results, are largely due to putting the sacrificial iron nails into the crucible at the beginning. It's like putting cake and asparagus in front of a child at the same time, and expecting the results to match your wishes. Some of the desirable metals will never make it into solution in a form that will be replaced by the iron, because the acid and iron are mutually consuming from the moment a mobile acid forms.

Thays what i was thinking, especially early in the video when he mentioned affinities between copper and zinc. Under some conditions affinities can differ driving a reaxtion one way or the other, so under the ones he was using, copper had a higher affinity than zinc so more zinc was left over.

Several metals have a high affinity for sulfur, meaning that they readily form compounds with sulfur. Some examples of metals with a high affinity for sulfur include: Lead: Lead has a high affinity for sulfur, and the two elements readily form compounds such as lead sulfide (PbS) and lead disulfide (PbS2). Copper: Copper has a high affinity for sulfur, and the two elements readily form compounds such as copper sulfide (CuS) and copper disulfide (CuS2). Mercury: Mercury has a high affinity for sulfur, and the two elements readily form compounds such as mercury sulfide (HgS) and mercury disulfide (HgS2). Nickel: Nickel has a high affinity for sulfur, and the two elements readily form compounds such as nickel sulfide (NiS) and nickel disulfide (NiS2). Iron: Iron has a high affinity for sulfur, and the two elements readily form compounds such as iron sulfide (FeS) and iron disulfide (FeS2). Cobalt: Cobalt has a high affinity for sulfur, and the two elements readily form compounds such as cobalt sulfide (CoS) and cobalt disulfide (CoS2). Manganese: Manganese has a high affinity for sulfur, and the two elements readily form compounds such as manganese sulfide (MnS) and manganese disulfide (MnS2). Zinc: Zinc has a high affinity for sulfur, and the two elements readily form compounds such as zinc sulfide (ZnS) and zinc disulfide (ZnS2). Tin: Tin has a high affinity for sulfur, and the two elements readily form compounds such as tin sulfide (SnS) and tin disulfide (SnS2). Tungsten: Tungsten has a high affinity for sulfur, and the two elements readily form compounds such as tungsten sulfide (WS2) and tungsten disulfide (W2S3). Molybdenum: Molybdenum has a high affinity for sulfur, and the two elements readily form compounds such as molybdenum sulfide (MoS2) and molybdenum disulfide (MoS3). Platinum: Platinum has a high affinity for sulfur, and the two elements readily form compounds such as platinum sulfide (PtS) and platinum disulfide (PtS2). It is worth noting that the affinity of a metal for sulfur can vary depending on the specific conditions under which the reaction is taking place, such as temperature and the presence of other elements. More metals? Gold: Gold has a high affinity for sulfur, and the two elements readily form compounds such as gold sulfide (AuS) and gold disulfide (AuS2). Silver: Silver has a high affinity for sulfur, and the two elements readily form compounds such as silver sulfide (Ag2S) and silver disulfide (Ag2S2). Palladium: Palladium has a high affinity for sulfur, and the two elements readily form compounds such as palladium sulfide (PdS) and palladium disulfide (PdS2). Cadmium: Cadmium has a high affinity for sulfur, and the two elements readily form compounds such as cadmium sulfide (CdS) and cadmium disulfide (CdS2). Antimony: Antimony has a high affinity for sulfur, and the two elements readily form compounds such as antimony sulfide (Sb2S3) and antimony disulfide (Sb2S5). Gallium: Gallium has a high affinity for sulfur, and the two elements readily form compounds such as gallium sulfide (Ga2S3) and gallium disulfide (Ga2S5). Selenium: Selenium has a high affinity for sulfur, and the two elements readily form compounds such as selenium sulfide (SeS2) and selenium disulfide (SeS4). Tellurium: Tellurium has a high affinity for sulfur, and the two elements readily form compounds such as tellurium sulfide (TeS2) and tellurium disulfide (TeS4). I hope this information is helpful. Let me know if you have any other questions. Please lost those metals in ascending order according to thier affinity with sulfur. Sure, here is a list of the metals I mentioned earlier, arranged in ascending order according to their affinity for sulfur: Lead Copper Mercury Nickel Iron Cobalt Manganese Zinc Tin Tungsten Molybdenum Platinum Gold Silver Palladium Cadmium Antimony Gallium Selenium Tellurium It is worth noting that the affinity of a metal for sulfur can vary depending on the specific conditions under which the reaction is taking place, such as temperature and the presence of other elements. This list represents a general trend and should not be taken as a definitive ranking of the metals' affinities for sulfur.

A little late to the party but the list above is indeed a good indication as to whether a metal can form a stable sulfide, and indeed if there is a common stable sulfide of a certain metal it can likely be used in some contexts as a sulfide sponge. However, this is not quantitative or predictive by any means. The question you really want to answer here is for which metals is the pure metal more stable than the sulfide. (I.e. how exothermic is this reaction: M + x/8 S8->MSx ) it turns out, the exothermicity of this reaction is known for many sulfide phases and is called the Enthalpy of formation or heat of formation of the sulfide. The more negative the heat of formation is the more stable this sulfide is. That means that if you combine a metal sulfide with a pure metal and the sulfide of that pure metal has a more negative heat of formation than the Metal in the sulfide, then the sulfur should transfer to the metal with the more negative heat of formation provided you get it hot enough and the sulfur doesn’t oxidize in the process. (overall reaction: MSx + n E -> m ESy + M). This could function as a quantitative scale for you to use certain metals as a sulfur sponge. The NIST database onlibe has all kinds of thermodynamic data on most common substances including solid metal sulfides. If you want to be really thorough then you would need to know the free energy of formation but entropy data is mostly harder to come by for many compounds so Enthalpy of formation (abbreviated *delta*H(subscript)f) is a good starting place. For example Galena (PbS) has an Enthalpy of formation of ca -98 kJ mol-1 and nickel sulfide (NiS) has a heat of formation of -88 kJ mol-1, then smelting NiS with Pb could give you Ni and PbS. However, like I said the free energies may change significantly at the high temperatures that you’re doing your smelts at and in a melt the Enthalpy of formations will be different in the liquid state anyway, so it’s really just a back of the envelope type thing. Don’t rely too heavily on this for sure fire results, it’s really just an indication that it could work potentially.

Thank you for taking us Along with you

Cu + CuO ----> 2 Cu2O Copper reacts with copper(II)oxide to produce copper(I)oxide. (You need to add nails, maybe not from the beginning but later during the smelting?) To test this theory, take the slag and reheat it with nails. This should produce additional copper.

Hi Jason, I am not a Chemist or Metallurgist, just a Mechanical Engineer. I would like to toss in my two cents purely from physical properties of different metals and chemicals. When heated, the mix melts in the crucible. Heavier metals stay in the bottom of the crucible. When poured, once again the heavy metals sink to the bottom of the cone. Right? For this to happen, the mix has to be really hot. If you observe your second, third and last pour, the mix was very thick meaning the mix is near to its solidifying temperature. I am visualizing that the mix has not melted sufficiently. The heavier metals are not hot enough to flow (observe the last few drops when you are pouring. they stuck to the sides of the crucible). In theory, the heavier metals are at the bottom of the crucible and are the last to flow out and as temp is low, all of them have not gone into the cone. What ever heavier metals which flowed out into the cone are not sufficiently hot and before they sink to the bottom of the cone, they solidified in the slag and you could not find a pyramid. This is just a theory. I am a big fan of yours, I learnt a lot about gold extraction from you. I may not be right but as you are asking why you did not find the metal pyramid, I thought I should toss my two cents.

Merry Christmas to you and your family. I enjoy how matter of fact you are with everything. It makes you hilarious for those of us that enjoy dry humor. The freezing shots of the molten pours are keepers while you explore this e-waste processing as both scientist and businessman.

Wish I would have known about you when I was running my technology business. Great job!

The metal coming out of the cone mold was so pretty! I was sad to see it melted again. It was so satisfying to see 200g scaled up to 2kg and get exactly 10x the weight as the result. 😍

You added 75 g of CuO (Mr. 79.5) which is about 0.94 mol. To reduce all of therm with iron, you need to react 0.63 mol of iron (~35.3 g) if it went to Iron(III) or 0.94 mol of iron ( 52.6 g) if it became Iron(II). So in the last experiment, not enough iron reacted.

BTW, even many mine operations don't refine their products, they sub that out. Near me is the Golden Queen mine. They make large ingots that are mostly silver by weight, and gold by value. The ingots are shipped to a refiner. It was a refiner in Japan last I heard, but just to give you an example. After refining, the refiner sends them funds based on everything contained in the ingots.

Sulfur reacts with all elements except for gold, platinum, iridium, tellurium, and the noble gases. This is right out of the chemistry book. Hope that helps fella.

You could try to chemically retrieve the gold/silver first, then smelt the copper based ore by itself. This may help with the electrolysis process too.

i think metals affinity for sulfure, and many other elements, could be highly dependent on pH, so it might not be so simple of a chart.

Add powdered charcoal and a lid to your crucible. The Carbon will react to any oxide pretty much and reduce it down while the lid keeps out further O2

The special "Reactivity Series in Sulfur" that you're looking for is the same one that you're familiar with. The weird experience you're having with Tin is because tin has weird solubility issues. It's essentially why it's not simple to recycle electronics.

@Reactivity series and Sulfur: The reactivity series is only valid for the metal and its ions in water solutions. It can give a hint on the behavior in other domains, but a lot of other effects can occur and are sometimes more important. Sulfides have strongly covalent bonds, so there are more things to factor in.

The reactions of metals and alloys with sulfur are governed by the same principles as metal-oxygen reactions. For many metals, however, sulfur behaves much more aggressively than oxygen. The stability of various metal sulfides as a function of temperature is given by the Ellingham diagram for the sulfides.

would more iron surface area increase the reduction rate of the oxides. Perhaps you can get cuttings from a machine shop to add to the crucible. You might see if you can get cast iron versus steel cuttings.

I do this type of stuff also myself it's very interesting at how much people throw away on a daily basis we need to start making better ways to recycle.

I think, first main error happened when crushing pcbs. The gold is mostly in form of just few microns thick "plating", often on plastic parts. When crushing and then shaker table some Gold gets lost in the waste fraction. Only solution ( besides incineration and chemical way) is to crush the pcbs much more finer.

Jason Super, like...!!!!💪👍

Be warry of adding sulfur to anything that you want to recover silver from...silver has a strong tendency to form silver sulfide ( this is why silver table utensils tarnishes slowly in air and faster with certain sulfur containing foods ), so you will lose silver to your slag. To be sure of recovering silver values, you might need either: - a longer time at molten, for the relatively large pieces of iron to fully react with silver sulfide - iron in smaller sized pieces ( to react faster ) - a more reactive metal ( like aluminum ) In all honesty, I would probably shy away from sulfur, unless you are also dealing with metals that are more reactive than iron. I have to wonder if your nails are sinking to the bottom of the crucible, thus becoming unavailable to react with lower density sulfur salt compounds higher in the crucible, so you get poor mixing, resulting in incomplete thermochemical reactions during your melt

Lol he's dinging the pan with the hammer and dropping the hammer and trying to explain hi tech big word stuff. And it's super funny. I'm glued.

Have you ever watched Sreetips videos? He does a lot of chemistry stuff to refine his gold, but the video on processing computer boards might interest you. Perhaps involving some acids would help in this computer project? I dunno. Love the content man!!

These videos may save me. Made a trip recently to Tennessee to do some panning and check a couple spots I researched. I brought home a bunch of quartz that looked good, and it's full of gold. More than I've ever seen, and I've only busted up a few fist sized rocks. I've got some fairly big quartz samples in the 40-50 lb range....all full of gold. Problem is that 90% of that gold is super fine flour gold. The rest is small flakes (like you would expect for the Coker area). There's so much that I'm really worried how I'm gonna separate it from the rock, and then collect it all. I know I'm missing a lot of it. I've used acid, crushed it down to powder and panned it using a magnifying glass, I have a little crucible and hand-held torch etc., but at this rate I should be finished (probably with only half the gold) around the year 2045. I've gotta go another way. I've never tried smelting, etc., but that's probably my route. I've been going through videos, built me a little furnace in the yard, and hopefully whichever process I pick will give me success.

Aqua Regia may be your friend. See Sreetips videos.

For metal reactivity. The general trend for sulfide should he similar to oxides. However if you want exact numbers. Look into the gibbs free energy. This is a measure of how thermodynamically stable something is, compared to its elemental form. So a gibbs free energy for CuS looks like -86 kj/mol. The lower the number the more stable the compound. If you are interested, i could try and compile a list of values from the published chemistry literature.

Copper Oxide is a oxidizing agent. Like Lead Oxide. You were reducing all of your metals into an oxide and driving them off into the refractory, or what you call your slag. Once it combined with the flux it dissolved all the metals into itself and thus mad a refractory. On your anode, don't smelt the slimes, if you do you'll melt your precious metals into the tin. There's nothing like trying to get the tin out and away from your precious metals. Take the pm's out first chemically, only other option is trying to slag the tin. Good luck with that. Tin dissolves in alkaline solutions. Maybe molten alkaline?

With circuit boards and getting precious metals narrow it down to where something connects. That is where the gold is. The other side of the board is going to be soldering. Lead. I have 4 lbs of just connections sitting in vinegar and salt bubbling in my garage.

I'm wondering about the affect the doping compounds used to make ICs have on the melts? Galium for instance; what does it do to the chemistry?

You also poured into cold metal. You had a thin layer of copper covering the entire cone then a smaller tip. Pour into hot cone.

Chemistry reactivity and smelting is slightly different, you are getting more of a alloy from smelting. I think your best bet is to get the most metal out of your concentrates and refine your slimes from electrolytic refining

If you check that last one out with a scan you may find it to be pure copper just a guess outstanding video two thumbs up my friend thank you

For saving time purpose.

Copper oxide and Copper are soluble in each other. They even form something like a "low" melting eutectic and are very soluble in each other in the liquid phase. Less so in solid state, but that's a different story. All other mixtures separated in the liquid state during smelting but this here does not.

Good!

I have some experience with sodium metabisulfide but none with pure elemental sulfur so I am sorry to not being able to help on your reactivity issue.

CuO at high temperatures turns into Cu2O (cca 1000 degrees Celsius). 2 CuO -> Cu2O + O, oxygen oxidazed the copper... I think, this happend (summary): 2 CuO + 2 Cu -> 2 Cu2O You end up with a lot of Cu2O and not much Cu.... Edit: Cu2O is reddish brown crystalline powder, maybe, that was it on the surface...

sometimes your pours look quite syrupy, is this because they need heating more or for longer? Would also love to see a pour into a very hot pyramid and continually heated with a slow cooling to see if the elements separate into more defined layers. Might make it easier to remove the top waste metals quicker.

Where's all the tin from the solder on your PC boards? In the #2? Depending on boards and pre processing(depopulating or selective depopulating), you could have large amounts to primarily tin. A lot of the sources of copper(like wire on resistors) is tin plated, so there's another source of tin. For a large scale processor, the tin would be a very important product, it's more valuable than copper.
